A molding apparatus comprises a first extruder and a second extruder and conduit fluidically connecting the extruders with a common mold wherein the at least one conduit has a conduit axis. The longitudinal axis of the first and second extruders extend at an angle of about 90° to a direction of flow in the conduit.

Microporous sheet product and methods of making and using the same. In one embodiment, the microporous sheet product is made by a process that includes melt-extruding a sheet material using an extrusion mixture that includes a thermoplastic polymer, a non-cross-linked elastomer having a molecular weight of at least 50,000 Da, and a compatibilizing agent. By way of example, the thermoplastic polymer may be a polyolefin, the non-cross-linked elastomer may be a polyisobutylene, and the compatibilizing agent may be mineral spirits. After extrusion, the sheet material may be cooled, and the sheet material may be stretched. The microporous sheet product may be used, for example, as a battery separator, as a food packaging material, as a diffusion barrier in the ultrafiltration of colloidal matter, and in disposable garments.

A system and method for reducing draw resonance of plastic material in the molten state, so-called melt, leaving an extrusion group of a plant for the production of plastic film, includes at least one thermostatically-controlled cylinder, having an embracement angle, of the melt on the cylinder, adjustable on the basis of the process rate, i.e. the linear movement speed of the plastic film, and/or on the basis of the temperature measured in the proximity of or in correspondence with the clamping area of the melt in a thermoforming, calibration and cooling group included in the plant and positioned downstream of the system.

A transparent, peelable polyester film is provided with clarity greater than 80% including a biaxially oriented polyester film as base layer (B) and an offline coated heat-sealable outer layer (A) that is peelable relative to ready-meal APET or RPET trays. The heat-sealable and peelable outer layer (A) includes from 85 to 99 wt % polyester and from 1 to 15 wt % other substances, the polyester including of from 25 to 95 mol % of units derived from at least one aromatic dicarboxylic acid and from 5 to 75 mol % of units derived from at least one aliphatic dicarboxylic acid. The polyester incorporates at least 10 mol % of units derived from diols having more than 2 carbon atoms. The mass of the dry outer layer (A) is from 1 to 5 g/m.sup.2. Production processes for the foregoing film, and use thereof as scalable film for ready-meal trays is also provided.
